Title: Hydraulic power transmission
Inventor: LAMBETH DENNIS ERNEST
IPC: B63H23/26
Filed: 1964-04-18
Abstract: 1,098,484. Hydrostatic transmissions. DOWTY TECHNICAL DEVELOPMENTS Ltd. April 13, 1965 [April 18, 1964], No. 16185/64. Heading F2C. An hydraulic power transmission comprises a tilting head pump 4 and a tilting head motor 2 mounted on a support maintaining the parallel tilting axes MT, PT and the shafts 1, 3 in fixed relative positions, a link 7 being pivoted at MP, PP to the motor and pump or extensions 8, 9 thereof. The pump is tilted from a dead centre position, wherein axes PT, MP, PP lie in a plane, by a servo 11 and thus causes tilting of motor 2. In the dead centre position the pump has zero displacement and the motor maximum displacement and the quadrilateral linkage MT-PT, PT-MP, MP-PP and MT-MP is such that initial movements of the pump to either side of the dead centre position, for forward and reverse, causes very small movement of the motor. The servo 11 has limited travel which normally prevents the motor reaching a dead centre position but should it be desirable for the motor to reach this position then a second servo acting on motor 2 is provided. The pump may have its zero displacement position not coinciding with its dead centre position so that the forward speed ratio can be greater than the reverse speed ratio. In Figs. 3, 4 (not shown), with shafts 1 and 3 parallel the linkage is arranged so that in the pump dead centre position the spacing PT-PP is shorter than MT-PT and the line PT-PP makes an acute angle with a plane through MT, PT. In Fig. 5 (not shown) the position of the axes is as in Fig. 4 but the shafts 1, 3 are at right angles. In Figs. 6, 7 (not shown), the shafts 1, 3 are inclined to each other and in the pump dead centre position, the distance PTPP is longer than PT-MT and the line PT-PP makes an acute angle with the plane through MT, PT. The pump or motor, Fig. 8 (not shown), has an annular flange on the driving shaft having sockets for ball joints on the ends of pistons slidable in a block rotatably mounted on a head which can pivot relative to the flange. The link 7 may be a pair of rods housing the hydraulic connections between the pump and motor.

Abstract: 1329640 Semi-conductor devices MITSUBISHI DENKI KK 21 May 1971 [22 May 1970 26 June 1970] 16365/71 Heading H1K A semi-conductor magnetic-to-electric transducer is based upon a transistor-type structure, with emitter, base and collector regions 38, 37, 36 and electrodes 44, 46, 41 respectively, in which the presence of a magnetic field, e.g. in a plane parallel to the major faces of the semiconductor body and along a line perpendicular to the direct path between the emitter and base electrodes 44, 46, varies the relative numbers of injected minority charge carriers in the base region 37 which reach the base electrode 46 and collector region 36 respectively. Output terminals in contact with the base and/or collector electrodes 46, 41 thus provide signals which vary in accordance with the direction of the magnetic field. The injection function of the emitter region 38 may alternatively be carried out by a Schottky contact, e.g. of Au or Al for a Si, Ge or III-V semi-conductor. The base electrode 46 is preferably situated on a diffused highly conductive region 45, although this may be omitted. The base region 37 may be formed by epitaxial deposition. Integrated structures comprising two or four transducers with a common collector region and interconnected so that the effects of an applied magnetic field on carrier transport properties in the component transducers co-operate to increase sensitivity are also described.

Title: Improvements in or relating to surface-active alkylbenzene sulphonate compositions
IPC: C11D1/22
Filed: 1950-07-06
Abstract: A propylene polymer fraction, B.P. 118-142 DEG  C., and averaging 9 carbon atoms per molecule is employed to alkylate benzol and the product is sulphonated and neutralized with soda.  In the same way a propylene polymer fraction, B.P. 175-225 DEG  C., averaging 12 carbon atoms, is employed to produce a C12 alkyl benzene sodium sulphonate. The two alkyl benzene sodium salts are mixed in specified proportions to yield an improved surface-active composition (see Group IV (c)).ALSO:A wetting composition consists of from 55 to 70 per cent by weight of an alkyl benzene sodium sulphonate averaging 9 carbon atoms in the alkyl group and from 45 to 30 per cent of an alkyl benzene sodium sulphonate averaging 12 carbon atoms in the alkyl group, both of the alkyl groups being formed from the molecules of polymerized olefines.  Preferably the alkyl group averaging 9 carbon atoms is formed from a propylene polymer fraction boiling over the range 118-142 DEG  C. and the alkyl group averaging 12 carbon atoms formed from a propylene polymer fraction boiling over the range 175-225 DEG C.  The mixtures dissolve in water, forming solutions which, having concentrations of up to 30 per cent, may be cooled to below room temperature and on subsequent warming not become turbid as is customarily the case.  The solutions may be used in textile treating baths, e.g. for scouring, bleaching, dyeing, fulling and the like. In examples, the compositions consist of the C9 and C12 alkyl benzene sodium sulphonates derived from the above-mentioned polymer fractions, the proportions being: (1) 70 : 30, (2) 60 : 40 and (3) 55 : 45 respectively.ALSO:A surface-active composition for use, e.g. in textile scouring, comprises 55-70 per cent by weight of an alkyl benzene sodium sulphonate averaging 9 carbon atoms in the alkyl group and 45-30 per cent of an alkyl benzene sodium sulphonate averaging 12 carbon atoms in the alkyl group, both of the alkyl groups being formed from the molecules of polymerized olefines.

The ram, platens and punch are each provided with a force sensing transducer 10, 10a, 10b, 10c in the form of a flanged metal cylinder 10, Figs. 2, 3 (not shown), provided with four strain gauges 14, 15, opposite pairs, orientated to sense longitudinal compression and circumferential expansion of the cylinder 10, being connected in opposition in a Wheatstone bridge. The output of each bridge may be connected via switch 30, Fig. 5, and an amplifier to a peak voltage indicator and meter 32 which indicates the total load or the partial loads applied by the individual platens. The output from the amplifier is also supplied to a density control circuit which energizes one of two relays should the signal exceed or fall short of a maximum or minimum predetermined voltage corresponding to maximum and minimum permissible densities of the compacted workpiece. These relays, when energized, may operate a visual or audible alarm or may actuate a gating device which causes those workpieces of which the densities lie either side of the preset limits to be ejected into two separate channels and those having acceptable densities into a third channel, Figs. 7, 8 (not shown). An overload detector 35 is also provided to shut the press off should the load provided by the main ram exceed a preset value. To calibrate the circuitry for operation a calibration bridge is provided which is connected to the output circuitry via switch 31. In the " zero " position of switch 31, the amplifier is automatically balanced to zero an automatic balancing circuit 34. In position " Cal. Meter " the meter 32 is calibrated to read the applied load in tons, and in position " Cal. limits " the maximum and minimum limits of the density control circuit 33 may be adjusted.
